My earliest attempt, make a 3-point connected stage for trapez-correction. I designed and built one, it worked, but was so flimsy. Didn't keep on improving it, but eventually an overhaul is due.
Another fun stage is to use a 70s style oil disc. They are available from Mathmos or used on ebay, but require some modification to the whole frame.
